A laboratory peptide is a research material with a specified amino-acid sequence. Synthetic peptides are commonly made by solid-phase synthesis and purified by chromatography. Our peptide products are supplied for in-vitro laboratory research only.
Read the FAQLyophilised means freeze-dried. Reconstitution means dissolving the powder in a suitable solvent. Solvent choice depends on the compound and assay; bacteriostatic water is not suitable for every experiment. The calculator checks quantity arithmetic, not solubility.
Open the calculatorFollow the compound-specific storage instructions and your laboratory protocol. Stability depends on the sequence, solvent, temperature and time. Avoid repeated freeze–thaw cycles where frozen storage is appropriate; no single shelf-life applies to every solution.
Handling & storagePeptides are usually described as chains of around 2–50 amino acids. Proteins contain one or more longer chains folded into a functional structure. Sequence length and molecular weight describe different things: two peptides with the same number of amino acids can have different masses. See the NHGRI peptide definition.
Peptides can be used to investigate molecular interactions and biological pathways. The useful experiment depends on the exact sequence and model. A laboratory finding does not establish a treatment benefit. Explore the BPC-157 evidence overview or CJC-1295 research and DAC distinctions for examples of how to read study results.
No. HPLC purity describes the target peak relative to detected peaks under the test method. Net peptide content describes the peptide fraction of the sample, excluding water, counter-ions and other non-peptide material. Neither figure alone tells you the mass of the intended peptide in a vial. Check which measurements the report actually includes.
A purity result also does not establish sterility or an endotoxin result. Read the published sample reports and supplier verification guide; compare the sample identity, test date, method and laboratory verification link. Technical background: GenScript peptide quality-control methods.
Milligrams (mg) and micrograms (mcg or µg) measure mass: 1 mg = 1,000 mcg. Millilitres (mL) measure volume. Concentration in mg/mL is mass divided by volume. On a U-100 scale, 100 marks correspond to 1 mL; those marks are not a peptide mass. Use the formulas and worked examples or the component worksheet for blends.
No. Our research-use materials are not approved for therapeutic, clinical or diagnostic use and are not for human or animal consumption. A named compound, a purity percentage or a published study does not change that product status. Read the research-use policy.

Open the available sample reports and check what was measured.
Read solvent considerations before using the concentration calculator.
Distinguish study preparations and measured outcomes from product claims.
Check concentration and sample-volume arithmetic using your vial mass and chosen volume. Solvent compatibility and experimental conditions must be established separately.
A short chain of amino acids (roughly 2–50) joined by peptide bonds. Shorter than a protein.
The building blocks of peptides and proteins. The order they're joined in defines the peptide's sequence.
The specific order of amino acids in a peptide. It determines the peptide's identity and properties.
The standard way laboratory peptides are made: amino acids are added one at a time onto a resin support, then cleaved and purified.
Dried under vacuum at low temperature into a stable powder ("cake"). How peptides are shipped for stability.
Dissolving a freeze-dried material in a measured volume of a solvent suitable for that compound and experiment.
Water containing 0.9% benzyl alcohol as a preservative. Check the product label and assay compatibility; adding it does not establish that a peptide solution is sterile.
To split a reconstituted solution into smaller single-use portions, so the rest can be stored without repeated freeze–thaw.
The peptide fraction of a sample, excluding non-peptide components such as water and counter-ions. It is distinct from HPLC purity and may be reported as a percentage.
A method-dependent measurement of the target component relative to detected components. HPLC purity is distinct from peptide content, sterility and endotoxin testing.
The analytical method used to separate and measure a peptide's purity and detect impurities.
An analytical method that measures mass-to-charge ratios. A molecular-mass match supports identity assessment but is not, by itself, complete sequence verification.

An inactive added ingredient — for example a bulking agent that stabilises the peptide during freeze-drying.
A sugar alcohol used as a bulking excipient. Cake size does not establish peptide mass or purity; check the formulation and analytical report.
